My experience with the Lamy 14K gold EF nib was excellent. I had tried the steel EF,F, and M and decided on the EF though there was not much difference in my experience from the EF to the F nib. I put the Lamy EF gold nib on a Lamy Studio pen and the nib gave a wetter flow to the ink and was more like a F in other pens. I was very happy with the results and my decision to purchase the gold nib. Outstanding service from Truphae.
